Product Term Allocator
The product term allocator controls how the five direct
product terms are assigned to each macrocell. For exam-
ple, all five direct terms can drive the OR function as shown
in
Figure 5
.
The product term allocator can re-assign other product
terms within the FB to increase the logic capacity of a mac-
rocell beyond five direct terms. Any macrocell requiring
additional product terms can access uncommitted product
terms in other macrocells within the FB. Up to 15 product
terms can be available to a single macrocell with only a
small incremental delay of t
PTA
,
as shown in
Figure 6
.
Note that the incremental delay affects only the product
terms in other macrocells. The timing of the direct product
terms is not changed.
